Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

it up to you how much time you wanna give your study. make time table according to you and revision time. prefer which chapter which you haven't completed yet then revise that chapter which you have already study.give extra time to solve question. make short notes so you can quickly revise the chapter.
